In a statement, Copelin says he took an over-the-counter nutritional supplement which is "legal and available to the public" but on the NCAA's list of prohibited substances, leading to the failed test and the NCAA's subsequent year-long suspension. Copelin admitted he did not clear the supplement with Missouri's conditioning staff before taking it.
